 The computer will pick four  color coded  'pegs',  using any combination of
 the 6 colors,  and hide them behind the box labeled CODE.   The codebreaker
 (you)  will  try to duplicate the exact colors and  positions of the secret
 code.   Each time the codebreaker places a row of code pegs,  the  computer
 will  give information  by placing  black and  white key pegs in  the boxes
 alongside the code pegs, or by leaving places in that box blank.   When the
 codebreaker duplicates the secretcode, the computer will place 4 black pegs
 alongside it,  and reveal the code.  Pressing the  backspace key will erase
 one color code backwards for correction.

 A Black Key Peg is placed IN ANY  of the 4 key peg positions for every code
      peg which is the same color and in exactly the same position as one of
      the code pegs in the hidden code.

 A White Key Peg is  placed  IN ANY  of the 4 key peg  holes for each hidden
      code peg which is matched in color but not position by a peg placed by
      the codebreaker.  For example, one white peg is placed if one red code
      peg is hidden,  and the codebreaker has placed 2 or more red code pegs
      in the wrong position.

 A Vacant Key Peg Hole is left for every code peg placed by the codebreaker
      that is incorrect.
